SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 453,942, dated June 9,1891.

Application filed January 17, 1891- $erial No. 378,12l- (No model.)

To all whom it may concern:

Be it known that I, THOR RYE,a citizen of the United States of America,residing at Minneota, in the countyof Lyon and State of Minnesota, haveinvented certain new and useful Improvements in Snow-Flows; andI dohereby declare the following to be a full, clear, and

. exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in snow-plows.

The object of the invention is to provide a device for removing snow andice from railway-tracks by elevating the same above the road-bed anddepositing it on either side of the track, and is further adapted to beused for removing sand or dirt from the track in case of land-slides;and it consists of a series of circular saws made up in sections, whichare mounted on a central shaft and provided with scoops or paddles forelevating the material elevated by said saws and depositing it in areceptacle carried by the frame above the road-bed, from which it isthrown out by revolving paddles on one or both sides of the track, asmay be desired; also, in providing means for raising and lowering thesaws above and below the level of the tracks.

In the accompanying drawings, forming part of this specification, Figurel is a side View, partly in section. Fig. Zis a plan view with the topof the structure removed.

The main truck or frame A- of the snow plow is of ordinary constructionand carries aboiler B, the usual fire-boxes, and appendages. To thesides of the frame and connected with the boiler are cylinders 'O O, thepistons of which are connected by pitmanrods to wrist-pins locatedbetween the sets of saw blades, and by means of these pistonrods thesaw-blades may be rotated.

D refers to pistons, the pitmen of which engage with the verticalcrank-shaft, upon which the fan or propeller-blades are secured.

The frame E is located preferably over the front portion of the boilerand is' provided with a series of openings 6 e, which are adapt ed to beclosed by doors a, the blades of the wheel F within the structure Ebeing of substantially the same height as the openings 6. The structureE is covered by a suitable plate or top, and the crank-shaft upon whichthe blades F are mounted has a bearing therein. A plate G extendsdownwardly from the superstructure E and is curved forward, slots beingprovided in the same on a line with the rails of the road. This curvedprojecting plate has also openings, through which the pitman-rods whichdrive the saw-blades pass, and also rearwardly projecting portions whichcarry truck-wheels, as shown. The curved plate Gis hinged or otherwisesecured to the boiler by means of brace-rods E so as to have a forwardor backward movement thereon, the forward movement of the upper endbeing limited by the stop E, formed by bending the floor, as shown.

H refers to side plates, between which is journaled a series of circularsaws I, made up of a suitable number of sections. The outer saw-blades 1are arranged in pairs, between which are located partition-plates 7c,and the outer saw-blades have rigidly secured thereto plates Separatedfrom the outer pairs of saw-blades are three or more blades K, betweenwhich are secured paddles, the central set of blades being adapted tooperate between the rails, while the outer sets operate beyond saidrails. The blades hereinbefore referred to are provided with enlargedcntral hubs, these hubs forming the bottom or base of theelevatingreceptaole. The wristpins to which the pitmen are connected aresecured to the central hub-and to the hubs of the cutters located overthe rails. In order that the back plate G and side plates may beadjusted, I provide said side plates and the back plate with links L,which carry loops M, having threaded openings, through which pass thethreaded ends of rods N, the opposite ends being fixed in suitablebrackets and provided with crank-handles. By turning these threaded rodsthe saws and the carryingframe can be raised and lowered, so that thesaws will operate upon the obstructions to the track either above orbelow the level of the rails.

A snow plow thus constructed may be pro be adapted to be coupled infront of an ordinary locomotive, and in practice the circular bladesbeing rotated at a very high rate of speed will loosen the snow or icewhich may be upon the road, and when loosened will be 5 elevated anddeposited in the receptacle E, from which it will be thrown by the wheelF, which also revolves at a high rate of speed.

The engine which propels the blades F is provided with the usual meansfor changing to the rotation of the crankshaft which it drives, so -thatthe propeller-blades may be driven with or against the sun to throw thematerial to the right or left of the track, as maybe desired. The upperportions of the side plates I 5 H carry a transverse partition-board O,which is arranged as shown, and said partitionboard has attached to itsrear outer corner curved plates 0, which cover the straight corners atthe junction of the curved plate G and rear ends of the upper portion ofthe side plates.

Having thus described my invention, what I claim as new, and desire'tosecure by Letters Patent, is-

1. The combination, in a snow-plow, of a series of circular serratedcutters arranged as shown, so that independent pairs of cutters will belocated immediately above the rails, said cutters having enlarged hubsand radiating carriers at right angles with the cutting blades,substantially as set forth.

2. The combination, in a snow-plow, of a series of circular cuttersjournaled upon a hinged frame, means for raising and lower- 5 ing saidhinged frame, and a receptacle, as

E, having a horizontally-revolving dischargewheel, substantially as setforth.

3. The combination, in a snow-plow, of a structure providing a sideframe, a curved 40 back plate G, secured thereto, a receptacle E,

having openings 0, said receptacle containing a discharge-wheel, avertical series of cutters having carriers mounted between the sideframes, means for vertically adjusting the cutters, and engines forrevolving the cutters and discharge-wheel, substantially as set forth.

l. The combination, in a snow-plow having cutters and elevators,substantially as shown, of the pivoted frame having truck-wheels at itsrear end, together with screw-threaded rods for vertically adjustingsaid frame, substantially as set forth.

5. The combination, in a snow-plow, radial cutters havingelevating-scoops, as shown, of a receptacle having ahorizontallyrevolving discharge-wheel, a partition-plate 0, carried bythe side frames II, said partition-board having curved plates 0 adjacentto its ends, substantially as set forth.

0. In an excavator for railways, the combination of a steam-boiler andframe carrying a rigid structure E, having openings 6 and doors forclosing said openings, a horizontally-revolving discharge-wheel locatedtherein, a front pivoted frame consisting of side pieces and a curvedplate G, pivotally connected to the boiler and frame, means forvertically adjusting the same, said frame inclosing a series of Verticalcutters, said outters being made up of segments attached to enlargedcentral hubs, and radiating partitions secured to the enlarged hubs andsegments, substantially as set forth.

In testimony whereof I ai'iix my signature in presence of two witnesses.

THOR RYE.
